Question

If A is a skew symmetric matrix then the trace of A
​

Answer 1

Answer:

scalar multiple of a skew-symmetric matrix is skew-symmetric. The elements on the diagonal of a skew-symmetric matrix are zero, and therefore its trace equals zero. , i.e. the nonzero eigenvalues of a skew-symmetric matrix are non-real.
